Be it known that l, GB01-zen LA VIGNE, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Belt-Cutting Machines, of which the following is a specification.

My invention relates'to improvements in implements for cutting off belting for use on machinery, for inserting and securing lacing staples, and for such other use as may be convenient, and its object is to provide a means whereby a belt may be easily and accurately cut.

I attain these objects by the mechanism shown in the accompanying drawing, in which Fig. 1 is a side elevation of the machine. Fig. 2 is a plan of the same. Fig. 3 isa sectional elevation of the same on the line 3 3 of Fig. 2 showing a cutting tool upon the cylinder.

Similar reference characters indicate similar parts throughout the several views.

ln the construction of this implement l provide a metal frame 1, having a floor 5 therein, and a permanently located metal anvil 13, which may be made separate from the floor 5, as in Fig. 3. et, in Fig. 3, represents a wooden anvil that is securely mounted upon the metal anvil 13, in posit-ion so that when the cutting tool 12 is forced through the belt 11 the edge will. bear upon, or come in -contact with the wood and will not dull or injure the cutting tool. This cutting tool is mounted upon a cylinder 7 that is provided with bearings at the ends, as at 9., whichy are mounted in the opening` 3 in the head 2 of the frame 1 in such a manner that it may be readily revolved therein. This cylinder is held in place in the frame, against the danger of endwise movementby means of the wooden anvil fl bymalring this anvil short enough to restbetween the inner surfaces of the bearings 8 and still allow the cylinder to revolve freely. This cylinder has a solid bearing 7 to receive and support the cutting tool 12, or the staple setting tool 12 and the machine is operated as follows: The belt 11 is'placed upon the table 5 with the part to be cut directly over the anvil 4, and the cylinder is made to revolve by any of the well known devices for operating the same `will come within thel scope of my invention.

At 6 I have shown ribs upon the sides of revolving,v or oscillating a cylinder of the the frame below, and back of the cylinder f bearings that kmay be utilized as supports in instances where such supports may be of utility in the working of the machine.

Having thus fully described my invention what l claim as new in the art, is:

1. In a machine for preparing belts for lacing, a body having a permanent table therein, a permanent anvil made integral with said body, a temporary anvil made of wood and securely connected with the permanent anvil, a cylinder revolubly mounted in the sides of the frame, said cylinder so constructed that the temporary anvil maybe utilized to prevent endwise movement ofy the cylinder, a cutting tool mounted upon the cylinder, and means for forcing the cylinder to revolve and the cutting tool to f cut a belt lying upon the temporary anvil.

2. ln a machine for preparing a belt for lacing, a body having a vpermanent table, and a temporary anvil therein, a cylinder made to revolve freely in the sides of the frame, said cylinder having a connecting ele.-

ment formed as a segment of a circle and the bearing ends of the cylinder so constructed that the temporary anvil may be utilized to prevent endwise movement of the cylinder, and means lfor revolving the cylinder to press one edge of the segmental body of the cylinder forcibly upon the surface of abelt that is placed upon the temporary anvil.

3. In combination with the elements covered in claim 2, a permanent anvil, and y `means for securing the temporary anvil safely upon the permanent anvil.
